Adaptable neurons are tied to learning and memory but also to neurological disorders. By studying fruit flies, researchers found a mechanism that controls neuroplasticity.

A neuroscientist and a clinician watched two new films about dementia. They recognised what they saw.
The equivalent of one bacon rasher was associated with 44% increased dementia risk.
If so, it's just one lifestyle risk among many others.
Nanodiamonds aren't just cellular bling: they could be used to better understand the development of cancer in our cells.
Currently, the only approved drugs for Alzheimer’s merely alleviate some of the symptoms — partially and temporarily — but do not stop the disease from progressing.
It was first officially described 115 years ago, but we still do not have a cure for Alzheimer's disease. The human brain is extremely complex, and Alzheimer’s is its most complex disease.
The final piece in the dementia puzzle is at the door.
A new study says African Americans with dementia carry a higher risk for COVID-19 than whites with dementia.
Because dementia patients are more likely to acquire COVID-19, and because so many live in close-quarter facilities – like nursing homes – it's critical to vaccinate them as quickly as possible.
Amyloid plaques are one cause of Alzheimer’s disease.
The researchers developed a molecule which works to stop toxic proteins from building up in the brain.
Being overweight or obese negatively affects brain health.

In this new study, people who were overweight had fewer brain cells and lower levels of blood flow compared to people of a normal weight.
The loss of neurons leads to degeneration.
Knowing what cells are more vulnerable could some day help researchers know why these cells are more vulnerable than others.
Air pollution exposure during mid to early life may be more important to developing Alzheimer’s disease than doctors realized.

The tiny air pollutants known as PM2.5, emitted by vehicles, factories and power plants, aren’t just a hazard for lungs. A study finds more brain shrinkage in older women exposed to pollution.
Our stomach and brain are connected through the ‘gut-brain axis’.

Our gut microbes play a key role in sending and receiving signals that influence the brain.
In the time of coronavirus, people with dementia and their caregivers need more support than ever.

New statistics show that people with dementia have been particularly vulnerable during the pandemic.
Around 50m people worldwide are living with dementia.
Architects need to learn to see dementia not as a disease but as a disability, and shift the design focus to spaces that can help maintain the everyday functions of people with the condition.
More than half of patients with dementia also suffer from depression. If the depression remains untreated, the associated memory and cognitive problems worsen. Conversely, a significant history of depression seems to be a risk factor for dementia.
Dementia and depression are two diagnoses that rob older adults of health and happiness. Despite their obvious differences, it is becoming ever more apparent that the two conditions are connected.
Even drinking fewer than 14 units of alcohol a week was damaging.
Drinking at "safe" levels was shown to reduce the amount of a person's total brain tissue.
Your medical team should determine whether you have dementia or just normal memory loss due to aging.

September is Alzheimer's Awareness Month and therefore a good time to talk about dementia. Alzheimer's is the most common dementia, but there are others to be aware of, a gerontologist explains.
More and more studies are revealing the cognitive effects of COVID-19.

Many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell to delirium to a higher risk of stroke. Down the road, will COVID-19 survivors face a wave of cognitive issues?
In healthy older people, loneliness has a pattern of stress response similar to that of people who are under chronic stress.

The social isolation older adults are experiencing as they try to stay safe from the coronavirus pandemic is raising new mental health risks, but people can take steps to protect themselves.

A blood test to detect Alzheimer's disease in people who have symptoms and even those who don't has been shown to work. Scientists still need to improve its accuracy rate to almost 100%, however.
